The word tattoo, or tattow in the 18th century, is a loanword from the Samoan word tatau, which means "to strike". The Oxford English Dictionary gives the etymology of tattoo as "In 18th c. tattaow, tattow. From Polynesian (Samoan, Tahitian, Tongan, etc.) tatau. In Marquesan, tatu." Ahead of the importation of the Polynesian word, the practice of tattooing had been described in the West as painting, scarring or staining.The etymology of the body modification term is not to be confused with the origins of the word for the military drumbeat or efficiency — see military tattoo. In this case, the English word tattoo is derived from the Dutch word taptoe.The very first written reference to the word tattoo (or tatau) appears in the journal of Joseph Banks (24 February 1743 – 19 June 1820), the naturalist aboard explorer James Cook's ship HMS Endeavour: "I shall now mention the way they mark themselves indelibly, every single of them is so marked by their humour or disposition".[5] The word tattoo was brought to Europe by Cook, when he returned in 1769 from his initial voyage to Tahiti and New Zealand. In his narrative of the voyage, he refers to an operation named "tattaw".

Tattoo enthusiasts could refer to tattoos as "ink", "pieces", "skin art", "tattoo art", "tats" or "work"; to the creators as "tattoo artists", "tattooers" or "tattooists"; and to areas where they operate as "tattoo shops", "tattoo studios" or "tattoo parlors".Mainstream art galleries hold exhibitions of both conventional and custom tattoo styles, such as Beyond Skin, at the Museum of Croydon. Copyrighted tattoo designs that are mass-made and sent to tattoo artists are identified as "flash", a notable instance of industrial style.[8] Flash sheets are prominently displayed in several tattoo parlors for the purpose of offering each inspiration and ready-produced tattoo pictures to clients.

The Japanese word irezumi means "insertion of ink" and can imply tattoos utilizing tebori, the classic Japanese hand technique, a Western-style machine or any approach of tattooing employing insertion of ink. The most frequent word utilized for standard Japanese tattoo styles is horimono. Japanese could use the word tattoo to mean non-Japanese styles of tattooing.
